Backstory- you are Scarletts younger sister she is currently 24 in this and you are 17 (I never see Scarlett povs about a sister or brother lol)

Scarletts pov-
Tonight is the night for the premier of Iron Man 2. After recently divorcing Ryan I decide to bring my younger sister y/n. She's quite reserved and quiet. She has never been ok, I'm pretty sure our parents divorce screwed her up. I love her to pieces and I would do anything to protect her, so when she told me she would come to the premier I was in utter shock. She normally hates attention but I think she is excited at the fact that this is my first marvel film after signing a 10 year contract.

Your pov-
I looked at myself in the mirror. God I hated dressing up but I was doing this for Scar as she practically raised me when mom and dad were arguing all the time when we were younger. (No hate to Scarletts parents btw) I looked at the skin tight black dress I was wearing. I turned to the side and the back to check myself out. Not too shabby i guess. My hair cascaded down past my shoulders with soft curls intertwining with eachother. The black heels were already hurting my feet.
It was a fact I overthink a lot. Everyone knows this as I zone out a lot as I look around and analyse everything.
Scar- " hey kid... y/n?....y/n? EARTH TO Y/N."
I quickly snapped out of my trance.
You- " yes sorry I'm ready to go"
Scar- " you sure your ready. And btw u look flawless. Catching all the ladies tonight"
You- " don't say that. It's weird"
Scarlett let's out a little giggle and comes over and pulls me in.
Scar- " remember to breathe sweetie"
You- " currently trying to do that"
Scar- " you don't have to come"
You- " nope I'm coming I have spent 3 hours getting ready. I'm not wasting this effort"

-Time skip to red carpet-

Scarlett walks ahead and all these bright lights are aggressively flashing with shouts
" SCARLETT OVER HERE" etc

I stand about 6 feet away from her. I'm trying to adjust to the surrounding real quick. Everything is a lot. The sounds the lights the air oh god. I feel my chest start to tighten. Not this again. I haven't told anyone about this. Except a doctor when I thought I was having a heart attack and it was just an anxiety attack. But that is what's happening right now. I can't just crumple on the carpet and rock back and forth. I would embarrass Scar so much. I try the breathing techniques they gave me. The doctor said if they get worse come back blah blah.

Scarlett-
I look over at my little sister and she has completely frozen up. I grab her hand and pull her close to me for some photos. She has tears in her eyes but she's putting on a smile. This is very strange so I whisper in her ear.
Scar- " you ok?"
She doesn't say anything she just nods and then proceeds to say " I need to the bathroom is that ok?"
Scar- " yeh of course do u need me to come with u?"
She shakes her head and quickly walks inside to the bathroom.

You-
I slam the door to the bathroom door and lock it. I let out a huge sob and start to hyperventilate. I could feel my heart beat racing faster and faster. My breaths getting shorter and shorter. I couldn't breathe. The thought of that made it so much worse.

Gwyneth Paltrow-
I am just zipping myself up after using the toilet and I hear someone come in slamming the doors. I hear cries and hyperventilating.
I open the stool door and I see Scarletts little sister. It was very clear she was having an anxiety attack. I got them a lot when I was younger. I knew how to help. I got down on the floor and rubbed her back she looked up and backed away.
G.P- " hey sweetie don't worry. I'm here follow my breathing. Just one breath at a time. Focus on me. Don't look anywhere else just at me."
Her breathing returned to normal and she was leaning into me so i wrapped my arm around her. Her mascara has run all down her face so i tried to rub some of it off. I got up to wet the toilet paper only to see Scarlett standing there in utter shock and state of panic.

Scarlett-
I see my little sister on the floor of the toilet and rush towards her. I squeeze her tight and she squeezes me back.
Scar- " your safe now. I'm sorry"
Y/n- " don't apologise it's my fault and thanks gwyneth.
G.P- " no problem kid see you out there. I have a great doctor you can see about anxiety attacks. I'll text Scar the link later"
I cuddle y/n tight and stroke through her hair. We sit there for about an hour because I realised she is the best thing I have in my life. She's so precious and she's been battling this on her own.
Scar- ". I love you"
You- " love you 2 sis"
